It's not unfortunate, it's on purpose. They don't HAVE to culture vaccines on aborted fetal tissue. They can use any biological culture medium-eggs, bacteria, you name it.
If they are able to inject you with fetal cells from another PERSON, it is essentially a transplant. People who receive transplanted organs have to take immune suppressive drugs for the rest of their lives. If they don't their immune systems would attack the transplanted organs, destroy the organ and remain in a hyper autoimmune state against the body. Besides vaccine adjuvants increasing immune response, fetal tissue (from another human) will causes the immune system to attack the host body, and there is no way to stop it without immunosuppressants .
Before the 20th century, autoimmune diseases were rare , if not non-existent.
Now this is the cause of almost every chronic disease. Lupus, Crohns, Diabetes ( yes!) Autism, Guilliane Barre , MS , Fibromyalgia, ALS, allergies (especially nut allergies)Seizure disorders, most childhood neurological impairments- encephalitis. These are all caused by inflammatory response trying to reject the adjuvants and fetal cell lines from a different human, a baby.There are also many other ingredients that increase the inflammatory response, like aluminum , squalane, etc. These vaccines are slow lethal cocktails.
So besides turning the soul against itself, these fetal cell vaccines also turn the body against itself. Lose lose.
